Description

Sensing method and apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411383479.1, filed on September 27, 2024, and entitled "Sensing method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a sensing method and apparatus. BACKGROUND

[0003] In international standard organizations such as the international telecommunication union (ITU) and the third generation partnership project (3 rd Generation partnership project, 3GPP), integrated sensing and communication (ISAC) has received more and more attention and research. In the ITU, ISAC is listed as one of the important development directions of future communication technologies. In the 3GPP, ISAC is also regarded as one of the key features of future communication technologies.

[0004] However, how to improve the sensing effect is a problem to be solved. SUMMARY

[0005] The present application provides a sensing method and apparatus, which can improve the sensing effect.

[0006] In a first aspect, a sensing method is provided. The method provided in the first aspect is applied to a first apparatus. In the absence of special description, the first apparatus in the present application can be a core network device, or a component (for example, a processor, a chip, or a chip system, etc.) in the core network device, or a logic module or software capable of realizing all or part of the functions of the core network device. For ease of description, the first apparatus is described below as an example.

[0007] Optionally, the first apparatus communicates based on a first communication protocol. The first communication protocol can be a 3GPP protocol.

[0008] The method includes: sending first information, the first information being used to indicate that sensing is performed based on a second communication protocol; and receiving second information, the second information being determined based on sensing performed based on the second communication protocol.

[0009] Those skilled in the art can understand that, in some scenarios (for example, indoor), it is difficult to achieve good results based on 3GPP protocol alone. In the above scheme, the first device can receive second information determined based on non-3GPP protocol sensing. For example, the first device can fuse the sensing results based on multiple communication protocols, thereby improving the sensing effect.

[0010] In some implementations, the second communication protocol includes at least one of a wireless local area network (WLAN) protocol, an ultra wide band (UWB) protocol, a Bluetooth protocol, an integrated mmWave (IMMW) protocol, an ultra-high reliability (UHR) protocol, or a spark link or nearlink protocol.

[0011] Based on the above scheme, the second information can be obtained based on one or more wireless short-range communication protocols. Those skilled in the art can understand that a wireless short-range communication system can have good sensing effect in some scenarios (for example, indoor). For example, with the help of a WLAN / UWB network with high indoor coverage density, the indoor sensing capability of the cellular network can be supplemented. For another example, with the help of the ultra-wide bandwidth (for example, up to about 2 gigahertz (GHz) bandwidth through frequency band splicing) of the UWB network, high range resolution can be achieved. Therefore, the above scheme can effectively improve the sensing effect.

[0094] In the present application, the terms and / or descriptions in different embodiments are consistent and can be referred to each other if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0095] I. In the present application, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the following cases: A exists alone, A and B exist together, B exists alone, where A and B can be singular or plural. In the literal description of the present application, the character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b and c can represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple.

[0096] II. In the present application, "first", "second", and various numerical numbers (for example, #1, #2, etc.) indicate the distinction for the convenience of description, and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different messages, etc., rather than to describe a specific order or sequence. It should be understood that the objects thus described can be interchanged under appropriate circumstances, so as to be able to describe schemes other than the embodiments of the present application.

[0097] III. In the present application, "when", "in the case of", "if" and other descriptions all mean that the device will make corresponding processing under certain objective circumstances, not limited to time, and also does not require the device to have a judgment action when implemented, nor does it mean that there are other limitations.

[0098] Four, in the present application, "indicate" or "for indicating" can include for direct indication (or explicit indication) and for indirect indication (or implicit indication). When describing a certain indication information for indicating A, it can include that the indication information directly indicates A or indirectly indicates A, and does not mean that A must be carried in the indication information. For example, in the case of indirect indication (or implicit indication), the receiving end of the indication information can obtain A according to the parameters indicated by the indication information, combined with other rules or combined with other parameters or by deduction.

[0099] Five, the indication mode related by the embodiments of the present application should be understood as covering various methods that can make the to-be-indicated party know the to-be-indicated information. The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of these sub-information can be the same or different, and the present application does not limit the sending method.

[0100] Six, in the present application, "protocol" can refer to a standard protocol in the communication field, which can include 5G protocol, new radio (NR) protocol and related protocols applied in future communication systems, and the present application does not limit this. "Predefined" can include predefinition. For example, protocol definition. "Preconfigured" can be realized by pre-saving corresponding code, table or other methods that can be used to indicate related information in the device, and the present application does not limit the implementation method.

[0101] Seven, in the present application, "communication" can also be described as "data transmission", "information transmission", "data processing" and the like. "Transmission" includes "sending" and "receiving". Exemplarily, the transmission can be uplink transmission, for example, the terminal device can send a signal to the network device; the transmission can also be downlink transmission, for example, the network device can send a signal to the terminal device; the transmission can also be sidelink transmission, for example, the terminal device can send a signal to another terminal device. Exemplarily, "transmission" can be air interface level transmission, or can be signal sending at chip input (I) / output (O) port, rather than air interface level transmission.

[0102] Eight, in the present application, "message", "information", "signal" or "information element (IE)" and the like can be used interchangeably, and the name of the message or information is not limited in any way, as long as the corresponding function can be realized.

"Receiving information from XX (device), or receiving information from XX (device)" can be understood as the source of the information is the device, which can include receiving information from the device directly or indirectly. The information between the source and the destination of the information transmission may be processed as necessary, such as format change, etc., but the destination can understand the effective information from the source. Similar expressions in this application can be similarly understood, and will not be repeated here. In addition, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can be between devices, for example, between network devices and terminal devices through the air interface, respectively sending or receiving, "sending" or "receiving" can also be within the device, for example, between components, modules, chips, software modules or hardware modules within the device through bus, wiring or interface.

[0104] Ten, in this application, the words "exemplarily", "such as" and the like are used to represent examples, illustrations or descriptions, and to present concepts in a specific way. Any embodiment or design scheme described as "example" in this application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In the embodiments of this application, "of", "corresponding", "corresponding" and "associated" can be used interchangeably at times. It should be pointed out that when the distinction is not emphasized, the meanings expressed are consistent.

[0105] Eleven, in this application, configuration can be signaling configuration, which can also be described as configuration signaling. For example, signaling configuration includes configuration by signaling sent by a network device, which can be radio resource control (RRC) message, downlink control information (DCI), or system information block (SIB). For another example, signaling configuration includes configuration between network devices. Among them, network devices can include access network devices, core network devices, or management plane devices, etc. Optionally, signaling configuration can also be configured to a terminal device or a network device by preconfigured signaling, or configured to a terminal device or a network device by preconfiguration. Here, preconfiguration is to define or configure the value of the corresponding parameter in advance in the protocol, and store it in the terminal device or the network device when communicating with the terminal device or the network device. The preconfigured message can be modified or updated under the condition that the terminal device or the network device is connected to the network.

The network device can also be referred to as an access network device or an access network node. It can be understood that in systems using different wireless access technologies, the names of devices with network device functions can be different. For convenience of description, the apparatuses providing wireless communication access functions for terminal devices in the embodiments of the present application are collectively referred to as base stations.

The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device in device to device (D2D) communication. The embodiments of the present application are not limited in this regard.

[0116] In the embodiments of the present application, the device for implementing the function of the terminal device can be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip or a chip system, which can be installed in the terminal device. The chip system can be composed of a chip, or can include a chip and other discrete devices. In the technical solutions of the embodiments of the present application, the device for implementing the function of the terminal device is a terminal device, which can also be referred to as a terminal. In the following description, the terminal device can be taken as an example of a UE.

[0117] The roles of the base station and the terminal can be relative, for example, the helicopter or the drone 112i in FIG. 1 can be configured as a mobile base station, and for those terminals 112j accessing the wireless access network 110 through 112i, the terminal 112i is a base station; but for the base station 111a, 112i is a terminal, that is, 111a and 112i communicate through a wireless air interface protocol. Of course, 111a and 112i can also communicate through a base station-to-base station interface protocol, in which case 112i is also a base station relative to 111a. Therefore, the base station and the terminal can be collectively referred to as a communication device, and 111a and 111b in FIG. 1 can be referred to as a communication device with a base station function, and 112a-112j in FIG. 1 can be referred to as a communication device with a terminal function.

[0118] The network device and the terminal device can communicate through a wireless link. The transmission link from the network device to the terminal device can be referred to as a downlink (DL) or a downlink channel, for transmitting a downlink signal. The transmission link from the terminal device to the network device can be referred to as an uplink (UL) or an uplink channel, for transmitting an uplink signal. The transmission link from one terminal device to another terminal device can be referred to as a sidelink (SL) or a sidelink channel, for transmitting a sidelink signal.

[0119] In recent years, wireless sensing technology has attracted widespread attention in the academic community. Wireless sensing technology analyzes the changes of wireless signals in the propagation process to obtain the characteristics of the signal propagation space (or channel) to achieve sensing of the scene.

[0120] Radar is a classic wireless sensing means and is widely used in agriculture, meteorology, and other fields. The basic principle of radar can be that the transmitter transmits a specific waveform signal, which is received by the receiver through the wireless channel. Signal processing combined with the transmitted signal and the received signal can extract the characteristics of the target of interest in the wireless channel.

[0121] The main function of a wireless communication system is to exchange information between transceivers, and its basic principle is also that the transmitting end transmits a specific waveform signal, which is received by the receiver through the wireless channel, and the signal is demodulated after signal processing to demodulate the signal transmitted by the transmitting end. From the entire physical process of transmission, transmission, and reception, the processes of radar and wireless communication are very similar. How to integrate wireless communication and sensing technology to perceive the surrounding environment while communicating has become a hot research topic.

[0122] FIG. 2 is a schematic diagram of some communication systems. FIG. 2 shows a plurality of nodes, between which communication can take place. The solid lines connecting two nodes in FIG. 2 can represent that communication can take place between the two nodes. FIG. 2 is merely an example, and the communication systems in embodiments of the present application can include more nodes, and there can be other communication paths between the nodes, which are not shown in FIG. 2.

[0123] The communication system shown in FIG. 2 can include a UE, a base station (denoted as RAN in FIG. 2), a sensing service client, and at least one network function (NF). Exemplarily, the at least one NF can include at least one of a network exposure function (NEF), a unified data repository (UDR), a unified data management (UDM), an application function (AF), a network data analytics function (NWDAF), an access and mobility management function (AMF), a sensing function (SF), a gateway sensing center (GSC), or a sensing reference unit (SRU).

[0124] The NEF can expose some functions of the network to an application in a controlled manner. Exemplarily, the NEF can be located between the 5G core network and an external third-party application function (possibly also partially located in the AF), and is responsible for managing external applications that open network data. For example, other devices that want to access internal data of the 5G core network must go through the NEF. The NEF can provide corresponding security guarantees to ensure the security of external applications to the 3GPP network, provide QoS customization capabilities for external applications, mobility state event subscription, AF request distribution, and other functions. In future communication systems, the network exposure function can still be the NEF, or it can have other names, which are not limited by the present application.

[0125] The UDR can be used to store structured data information, including subscription information, policy information, and network data or service data with a standard format definition. In future communication systems, the unified data repository can still be the UDR, or can have other names, which are not limited in the present application.

[0126] The UDM can be used to manage and store user data (or subscription information) of terminal devices. For example, user identity information, authentication information, subscription information, policy information, and the like. The unified data management network element can provide query and update services for user data for other network elements. The UDM can support functions such as authentication, authorization, and key management of users. In addition, the UDM can update and synchronize user data according to the policy control of the network element. In the 5G communication system, the unified data management network element can be the UDM, and in future communication systems, the unified data management network element can still be the UDM, or can have other names, which are not limited in the present application.

[0127] The AF can refer to various services of the application layer. The AF can be used to deliver application-side requirements to the network side. For example, the requirements can include QoS requirements or user state event subscriptions. The AF can provide service data of various applications to the control plane network element of the operator's communication network, or obtain data information and control information of the network from the control plane network element of the communication network. In the 5G communication system, the application function network element can be the application function (application function, AF), and in future communication systems, the application function network element can still be the AF network element, or can have other names, which are not limited in the present application. For example, the application function network element can also be called an application server or a service server. In addition, the application function network element can be deployed by the operator network (for example, the AF can be an application inside the operator.), or can be deployed by a third party. For example, the AF can be a voice over long-term evolution (voice over long-term evolution, Volte) AF, or a third-party AF (such as a video server, a game server).

[0128] The NWDAF can collect data from various NFs, AFs (for example, through NEF), UEs, or network management, and perform analysis and prediction. The NWDAF can have data collection, training, analysis, and inference functions. Based on the analysis and training of related data, the NWDAF can provide data analysis results to NFs, AFs, UEs, or network management systems, which can assist the network in selecting service quality parameters for services, or assisting the network in performing traffic routing, or assisting the network in selecting background data transmission strategies, and the like. In the 5G communication system, the network data analysis network element can be the NWDAF, and in future communication systems, the network data analysis network element can still be the NWDAF network element, or can have other names, which are not limited in the present application.

[0129] The AMF can be used for terminal attachment in a mobile network, a tracking area update process, an access and mobility management network element can provide non-access stratum (NAS) messages, complete registration management, connection management, reachability management, allocate a tracking area list (TA list), access authorization, authentication, and mobility management, etc., and transparently route session management (SM) messages to a session management network element. The AMF can provide a session management message transmission channel for the UE and the session management function (SMF), provide authentication and authorization functions when the user accesses, and access the terminal and the wireless core network control plane access point. In the 5G communication system, the access and mobility management network element can be the AMF, and in the future communication system, the access and mobility management function can still be the AMF, or can also have other names, which are not limited by the present application.

[0130] The GCS can complete the processing of the perception request of the perception service client. For example, the GSC can obtain the perception information of the target and return it to the perception service client. In the future communication system, the GCS can also have other names, which are not limited by the present application.

[0131] The SRU can be an SRU with a known location. The SRU can perform perception measurements and report the measurement values to the perception server. For example, the perception measurements can obtain reference signal time difference (RSTD), reference signal receiving power (RSRP), or UE receive (Rx)-transmit (Tx) time difference measurements, etc. The SRU can transmit a perception reference signal to enable a base station (e.g., TRP) to measure and report UL perception measurement values from the SRU at a known location. For example, the perception measurement results can include relative time of arrival (RTOA), UL angle-of-arrival (AoA), or Rx-Tx time difference of a base station (e.g., gNB), etc. The perception server can compare the SRU measurement values with expected measurement values at the known SRU location to determine correction terms for other nearby objects. Then, the DL and / or UL perception measurement values of the other objects can be corrected based on the previously determined correction terms. From the perspective of the perception server, the SRU function can be implemented by a UE with a known location. In other words, the SRU can be a UE.

[0132] The perception service client can be a logical functional entity. The perception service client can be an entity within a PLMN, such as an operation and maintenance (O&M) tool. The perception service client can also be an entity outside the PLMN. For example, a third-party positioning server deployed by a non-operator. The perception service client can initiate a perception request carrying parameters such as QoS, requiring to obtain the location information of one or more targets.

[0133] FIG. 3 is a schematic flowchart of a perception method 300 according to an embodiment of the present application. The method 300 improves the perception effect by scheduling a first terminal to perform perception based on a non-3GPP protocol. The optional operations in the method 300 are shown in dashed lines in FIG. 3. The method 300 is described by taking the interaction between the first terminal and a first device as an example.

[0134] Unless otherwise specified, the first terminal in the present application can be a terminal device, a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logic module or software capable of realizing all or part of the functions of the terminal device. For ease of description, the first terminal is taken as an example in the following description.

[0135] Unless otherwise specified, the first device in the present application can be a core network device, a component (for example, a processor, a chip, or a chip system, etc.) in the core network device, or a logic module or software capable of realizing all or part of the functions of the core network device. For ease of description, the first device is taken as an example in the following description.

[0136] For example, the first device can be an SF, an SF-control plane (CP), or an SF-user plane (UP).

[0137] The first device described above can communicate with the first terminal based on a first communication protocol. For example, the first communication protocol can be a 3GPP protocol, or a mobile communication protocol, or a cellular network protocol. For ease of description, the first communication protocol is taken as a 3GPP protocol in the following description.

[0138] The operations of the method 300 are described below in conjunction with FIG. 3.

[0139] S350, the first device sends first information to the first terminal, the first information being used to instruct the first terminal to perform perception based on a second communication protocol. Correspondingly, the first terminal receives the first information from the first device.

[0140] Exemplarily, the first device can send the first information to the first terminal based on a 3GPP protocol. Correspondingly, the first terminal can receive the first information from the first device based on the 3GPP protocol. In the embodiments of the present application, the interaction between the first device and the first terminal is based on the 3GPP protocol, which will not be described below.

[0141] The second communication protocol can be different from the 3GPP protocol. For example, the second communication protocol can be referred to as a non-3GPP protocol. For another example, the second communication protocol can include at least one of a wireless short-range communication protocol.

[0142] Exemplarily, the second communication protocol can include at least one of a wireless local area network (WLAN) protocol, an ultra-wideband (UWB) protocol, a Bluetooth protocol, an integrated millimeter wave (IMMW) protocol, an ultra-high reliability (UHR) protocol, or a star flash protocol.

[0143] The second communication protocol can be used to regulate perception-related operations.

[0144] For example, the WLAN protocol described above can be a perception-related protocol in the WLAN protocol. For example, institute of electrical and electronics engineers (IEEE) 802.11bf.

[0145] The UWB protocol described above can be a perception-related protocol in the UWB protocol. For example, IEEE 802.15.4ab.

[0146] The Bluetooth protocol described above can be a perception-related protocol in the Bluetooth protocol.

[0147] The IMMW protocol described above can be a perception-related protocol in the IMMW protocol.

[0148] The UHR protocol described above can be a perception-related protocol in the UHR protocol.

[0149] The star flash protocol described above can be a perception-related protocol in the star flash protocol.

[0150] Based on the above scheme, the second information can be obtained based on one or more wireless short-range communication protocols. Those skilled in the art can understand that a wireless short-range communication system can have better perception effect in some scenarios (for example, indoor). For example, with the help of a WLAN / UWB network with high indoor coverage density, the indoor perception capability of the cellular network can be supplemented. For another example, with the help of the ultra-high bandwidth (for example, up to about 2 gigahertz (GHz) bandwidth through frequency band splicing) of the UWB network, high distance resolution can be achieved. Therefore, the above scheme can effectively improve the perception effect.

[0151] S370, the first terminal determines second information based on the sensing according to the second communication protocol.

[0152] Exemplarily, the second information can be used to indicate measurement information and / or sensing result. For example, the second information can include the measurement information and / or the sensing result.

[0153] The measurement information can be preliminary data obtained by the first terminal based on the sensing according to the second communication protocol, for example, a measurement result of CIR or a measurement result of channel state information (CSI).

[0154] The sensing result can be a result obtained by processing based on the measurement information. The sensing result can reflect characteristics of the sensing target, for example, information such as number, position, distance, angle, speed, intensity, or material of the sensing target.

[0155] In some examples, the first terminal obtains the measurement information based on the sensing according to the second communication protocol. The measurement information is indicated by the second information.

[0156] In other examples, the first terminal obtains the measurement information based on the sensing according to the second communication protocol. Further, the method 300 can further include that the first terminal determines a sensing result according to the measurement information. The sensing result can be indicated by the second information.

[0157] The second information can also be referred to as sensing information, sensing measurement, or other names, which are not limited in the present application. The first terminal sending the second information to the first device can also be understood as the first terminal providing sensing measurement.

[0158] The measurement information can also be referred to as sensing measurement, measurement data, measurement result, sensing measurement result, or other names, which are not limited in the present application.

[0159] The sensing result can also be referred to as sensing processed result, result information, sensing target information, or other names, which are not limited in the present application.

[0160] S380, the first device receives the second information from the first terminal. The second information is determined based on the sensing according to the second communication protocol. Correspondingly, the first terminal sends the second information to the first device.

[0161] Those skilled in the art can understand that in some scenarios (for example, indoor), it is difficult to achieve good results based on 3GPP protocol alone. In the above scheme, the first device can receive second information determined based on sensing according to a non-3GPP protocol. For example, the first device can fuse the sensing results obtained based on multiple communication protocols, thereby improving the sensing effect.

[0162] Optionally, the measurement information comprises at least one of:

[0163] a reference time of the measurement information. Alternatively, the reference time of the measurement information can be referred to as measurement reference time. The reference time of the measurement information can indicate the universal time coordinated (UTC) time when the measurement based on the second communication protocol is performed. For example, the reference time of the measurement information can be in the form of YYMMDDhhmmssZ. Wherein, "YY" can represent the year. "MM" can represent the month. "DD" can represent the day. "hh" can represent the hour. "mm" can represent the minute. "ss" can represent the second. "Z" can represent the offset.

[0164] an identifier of the second device configured to assist the sensing based on the second communication protocol. For example, when the second communication protocol is a WLAN protocol, the second device can be a WLAN AP. For another example, when the second communication protocol is a UWB protocol, the second device can be a UWB anchor.

[0165] a RSSI of the second device. For example, when the second communication protocol is a WLAN protocol, the RSSI can indicate the AP RSSI measured at the target for a beacon frame, a probe response frame, or a measurement pilot frame. The unit can be decibel (dBm).

[0166] a CIR in-phase component (CIRI) of the CIR.

[0167] a CIR quadrature-phase component (CIRQ) of the CIR.

[0168] CIR sample time interval (cirSTI) of the CIR.

[0169] CIR sample index (cirSI) of the CIR.

[0170] Reference tap (refTap) of the CIR. For example, the reference tap of the CIR can indicate a time stamp of a reference tap of the measured CIR. For another example, the reference tap of the CIR can indicate a reference tap type.

[0171] Time stamp of the CIR.

[0172] In some examples, in a case that the second information comprises the measurement information, the second information can carry an information element (IE) as shown in Table 1.

[0173] Table 1: Fields of the measurement information

[0174] The " / " in Table 1 can represent "and / or". The fields of the measurement information can comprise some or all of the fields in Table 1. The fields of the measurement information can comprise fields other than those in Table 1, which are not limited in the present application.

[0175] Exemplarily, in a case that the second communication protocol comprises a WLAN protocol and / or a UWB protocol, the field "measurement list" can provide a list of WLAN APs and / or UWB anchors. For example, the number of WLAN APs and / or UWB anchors indicated by the field "measurement list" is up to 64.

[0176] Exemplarily, in a case that the second communication protocol comprises a WLAN protocol and / or a UWB protocol, the field "identity of the second device" can indicate a WLAN AP identity and / or a UWB anchor identity. Wherein, the "WLAN AP identity" can indicate a basic service set identifier (BSSID) and / or a service set identifier (SSID) of a wireless network served by the WLAN AP. Wherein, the "UWB anchor identity" can indicate a device identity (ID) and / or a personal area network (PAN) ID of a wireless network served by the UWB anchor.

[0177] Exemplarily, the field "service flag" can indicate whether the measurement information is obtained for a second device of a service or a second device of a non-service.

[0178] The descriptions of the other fields in Table 1 are referred to the foregoing, and will not be repeated.

[0179] Based on the above scheme, the measurement information can comprise one or more fields, and the first device can determine the awareness result according to one or more fields in the measurement information.

[0180] Optionally, the awareness result comprises at least one of:

[0181] a reference time of the awareness result. Alternatively, the reference time of the awareness result can be referred to as a result reference time. The reference time of the awareness information can indicate a UTC time at which the awareness result is processed based on the second communication protocol.

[0192] The fields of the sensing result can comprise some or all of the fields in Table 2. The fields of the sensing result can comprise fields other than those in Table 2, which are not limited by the present application. The description of each field in Table 2 is described above and will not be repeated here.

[0193] In some examples, after receiving S350, the first terminal can actively perform S370 and S380.

[0194] In some other examples, the first terminal performing S370 and S380 can be scheduled by the first device. Details are described below.

[0198] In some possible implementation manners, S370 comprises: in response to the third information, the first terminal determines the second information based on the sensing based on the second communication protocol.

[0199] In some possible implementation manners, S380 comprises: in response to the third information, the first terminal sends the second information to the first device.

[0200] The above-mentioned “request A” can be understood as query A, or instructing the first terminal to report A. For example, the third information used for requesting the sensing result can be understood as the third information used for querying the sensing result, or understood as the third information used for instructing the first terminal to report the sensing result.

[0201] In some examples, in a case that the third information is used for requesting the measurement information, the third information can carry the IE as shown in Table 3.

[0202] Table 3 Field 1 of the third information (or referred to as sensing request)

[0203] The fields of the third information can comprise some or all of the fields in Table 3. The fields of the third information can comprise fields other than those in Table 3, which are not limited by the present application.

[0204] The field "requested measurement information" can be used to indicate the specific content requested by the first device, or the field "requested measurement information" can be used to indicate the specific content to be fed back by the first terminal.

[0205] For example, the field "requested measurement information" is used to indicate at least one of the following:

[0206] the reference time of the measurement information.

[0207] the identity of the second device.

[0208] the RSSI of the second device.

[0209] CIRI.

[0210] CIRQ.

[0211] cirSTI.

[0212] cirSI.

[0213] the refTap of CIR.

[0214] the timestamp of CIR.

[0215] For example, in the case where the field "requested measurement information" is used to indicate CIRI, the second information sent by the first terminal to the first device can carry a field indicating CIRI.

[0216] For example, the field "auxiliary availability" can be used to indicate whether the first terminal can request additional auxiliary data from the first device (or other devices). If the field "auxiliary availability" indicates yes (or, allowed, or, true), the first terminal can request auxiliary data from the first device. If the field "auxiliary availability" indicates no (or, not allowed, or, false), the first terminal can not request auxiliary data from the first device.

[0217] In some examples, in the case where the third information is used to request the awareness result, the third information can carry the IE as shown in Table 4.

[0218] Table 4 Field 2 of the third information

[0219] The fields of the third information can include some or all of the fields in Table 4. The fields of the third information can include fields other than those in Table 4, which are not limited in the present application.

[0220] The field "requested result" can be used to indicate the specific content requested by the first device, or the field "requested result" can be used to indicate the specific content to be fed back by the first terminal.

[0221] For example, the field "requested result" is used to indicate at least one of the following:

[0222] tarNum.

[0223] tarPos.

[0224] tarVel.

[0225] tarRange.

[0226] tarAng.

[0227] tarAmp.

[0228] The timestamp of the sensing result.

[0229] For example, in the case where the field "requested result" is used to indicate tarNum, the second information sent by the first terminal can carry a field used to indicate tarNum.

[0230] The description of the field "auxiliary availability" is described in the example of Table 3, which is not repeated here.

[0231] The third information described above can also be referred to as a sensing request, a sensing measurement request, a request sensing information or other names, which are not limited in the present application. The first device sending the third information to the first terminal can also be understood as the first device requesting a sensing measurement from the first terminal.

[0232] Based on the above scheme, the first device can request to feed back the sensing result or measurement information obtained based on the second communication protocol through the third information, so as to trigger the sensing of the first terminal based on the second communication protocol.

[0233] Exemplarily, the S360 and the S370 can be referred to as a sensing information transfer procedure. Alternatively, the S360 and the S380 can be referred to as a sensing information transfer procedure.

[0234] The sensing information transfer procedure can include only the S380, or include the S360 and the S380.

[0235] The following introduces a related example of a capability transfer procedure.

[0236] In some possible implementation manners, before the S350, the method 300 further includes: S320. The following introduces in detail in combination with FIG. 3.

[0237] The S320 includes: receiving, by the first device, fourth information from the first terminal. The fourth information is used to indicate that sensing based on the second communication protocol is supported. Correspondingly, the first terminal sends the fourth information to the first device.

[0238] In some possible implementation manners, the S360 includes: based on the fourth information, sending, by the first device, first information to the first terminal. The first information is used to instruct the first terminal to perform sensing based on the second communication protocol.

[0239] The first device can determine whether to schedule the first terminal to perform sensing based on the second communication protocol according to the capability of the first terminal.

[0240] In another example, the first terminal can send fourth information' to the first device. The fourth information' can be used to indicate that the first terminal does not support sensing based on the second communication protocol.

[0241] Exemplarily, the fourth information and the fourth information' can be different states of a same field. For example, the fourth information can indicate on, yes, or true, indicating that the first terminal has the capability of performing sensing based on the second communication protocol. For example, the fourth information' can indicate off, no, or false, indicating that the first terminal does not have the capability of performing sensing based on the second communication protocol.

[0242] Exemplarily, the fourth information can further indicate a sensing method (for example, ranging, angle measurement, or speed measurement) supported by the first terminal, a sensing capability (for example, obtaining a ranging resolution, an angle measurement resolution, or a speed measurement resolution) or some common parameters (for example, a sensing frequency, mono-static, bi-static, or multi-static) required by the sensing method.

[0243] The fourth information can also be referred to as capability information, provide capabilities information, or other names, which are not limited in the present application. The first terminal sending the fourth information to the first device can also be understood as the first terminal providing capabilities to the first device.

[0244] Based on the above scheme, the first device can receive the capability information of the first terminal, so as to determine that the first device is instructed to perform sensing based on the second communication protocol. The above scheme can avoid the first device scheduling a device without corresponding capability to perform sensing based on the second communication protocol, thereby saving signaling overhead.

[0245] Optionally, the fourth information is further used to indicate at least one of the following:

[0246] Supporting single-base sensing.

[0247] Supporting double-base sensing.

[0248] Supporting multi-base sensing.

[0249] Supported distance resolution.

[0250] Supported angle resolution.

[0251] Supported speed resolution.

[0252] Supported maximum sensing distance.

[0253] Supported maximum sensing angle.

[0254] Supported maximum sensing speed.

[0255] Supporting feedback of measurement information.

[0256] Supporting feedback of sensing results.

[0257] Supported second device. Wherein the second device can be used for auxiliary sensing based on the second communication protocol.

[0258] In some examples, the fourth information can carry an IE as shown in Table 5.

[0259] Table 5 Fields of the fourth information (or called capability information)

[0260] The fields of the fourth information can include some or all of the fields in Table 5. The fields of the fourth information can include fields other than those in Table 5, which are not limited by the present application.

[0261] Exemplarily, the field “mode” can indicate the mode supported by the first device. For example, the first device can support at least one of the following:

[0262] The first mode. For example, the first mode can be referred to as a standalone mode, or referred to as a UE standalone mode.

[0263] The second mode. For example, the second mode can be referred to as a UE-assisted mode.

[0264] The third mode. For example, the third mode can be referred to as a UE-based mode.

[0265] Specific examples of the three modes will be described later, which will not be described here.

[0266] Exemplarily, the field “sensing capability” can indicate at least one of the following:

[0267] Single-base sensing.

[0268] Double-base sensing.

[0269] Multi-base sensing.

[0270] Distance resolution.

[0271] Angle resolution.

[0272] Speed resolution.

[0273] Maximum sensing distance.

[0274] Maximum sensing angle. For example, the field of view (FOV) of the maximum sensing.

[0275] Maximum sensing speed.

[0276] For example, the field "sensing capability" indicates single base sensing, which means the first device supports single base sensing. For another example, the field "maximum sensing distance" indicates that the maximum sensing distance is A, which means the maximum sensing distance supported by the first device is A.

[0277] The field "supported measurement" can indicate the content of measurement supported by the first terminal. For example, the field "supported measurement" can indicate at least one of the following:

[0278] RSSI.

[0279] Measurement information. For example, the measurement information can include CIR.

[0280] Sensing result.

[0281] For example, the field "supported measurement" indicates RSSI, which means the first terminal has the capability of measuring (or determining, or obtaining) RSSI.

[0282] For another example, the field "supported measurement" indicates measurement information, which means the first terminal has the capability of measuring (or determining, or obtaining) measurement information.

[0283] For another example, the field "supported measurement" indicates sensing result, which means the first terminal has the capability of measuring (or determining, or obtaining) sensing result; or, which means the first terminal has the capability of sensing processing. The capability can be used to obtain sensing result.

[0284] Exemplarily, the field "supported second device information" can indicate the identity of the second device and / or the location information of the second device.

[0285] Exemplarily, the field "supported periodic reporting" can indicate that the first terminal supports periodically sending the second information (used to indicate sensing result and / or measurement information). For example, the presence of the field "supported periodic reporting" means that the first terminal supports periodically sending the second information; the absence of the field "supported periodic reporting" means that the first terminal does not support periodically sending the second information.

[0286] Exemplarily, the field "idle state measurement" can indicate that the first terminal needs to perform measurement in the case that the first terminal is in idle state. For example, the field "idle state measurement" exists, indicating that the first terminal needs to perform measurement in the case that the first terminal is in idle state.

[0287] Exemplarily, the field "support scheduled sensing request" can indicate whether the first terminal supports sensing in a scheduled manner. For example, if the field exists, it can indicate that the first terminal supports sensing request in a scheduled manner, in other words, can indicate that the first terminal supports sensing mode. The field can indicate support for the element "scheduled sensing time" in the element "Common IEs Request Sensing Information". For another example, the field can indicate the time base supported by the scheduled sensing time of each sensing mode. If the field does not exist, it can indicate that the first terminal does not support sensing request in a scheduled manner.

[0288] Exemplarily, the field "support periodic reporting with minimum millisecond interval" can indicate whether the first terminal supports periodically feeding back sensing results. For example, if the field exists, it can indicate the minimum millisecond periodic reporting interval supported by the sensing information of each sensing mode. For example, the field can support the subfield "reporting interval Ms" of the element "Periodical Reporting Criteria Ext" in the element "Common IEs Request Sensing Information". The field can also indicate the minimum millisecond reporting interval supported by periodic reporting.

[0289] Based on the above scheme, the first device can receive the capability information of the first terminal about sensing, so as to determine the sensing related configuration of the first terminal. For example, in the case that the first terminal supports feeding back measurement information, the first device can configure the first terminal to feed back measurement information.

[0290] In some examples, the first terminal can actively perform S320. That is, the first terminal can actively perform capability reporting.

[0291] In another examples, the first terminal performs S330, which can be scheduled by the first device. Details are described below.

[0292] In some possible implementation manners, before S320, the method 300 further includes S310. Details are described below in combination with FIG. 3.

[0293] S310, the first device sends fifth information to the first terminal, the fifth information being used for indicating whether feedback supports sensing based on the second communication protocol. Alternatively, it can be understood that the fifth information is used for indicating the first terminal to report capability.

[0294] Correspondingly, the first terminal receives the fifth information from the first device.

[0295] In some possible implementation ways, S320 comprises: in response to the fifth information, the first terminal sends fourth information (used for indicating support of sensing based on the second communication protocol) to the first device.

[0296] Exemplarily, the fifth information is further used for indicating the first terminal to feedback at least one of the following:

[0307] whether feedback sensing result is supported.

[0308] supported second device. Wherein the second device can be used for auxiliary sensing based on the second communication protocol.

[0309] In some examples, the fifth information can carry an IE as shown in Table 6.

[0310] Table 6 Fields of the fifth information (or called capability request)

[0311] The fields of the fifth information can include some or all of the fields in Table 6. The fields of the fifth information can include fields other than those in Table 6, which are not limited in the present application.

[0312] Exemplarily, the fifth information carries a field “mode”, indicating that the fifth information indicates that the fourth information fed back by the first device needs to carry the field “mode”.

[0313] The meanings of the above-mentioned fields can be referred to the description of Table 5, and will not be repeated here.

[0314] The above-mentioned fifth information can also be referred to as a capability request or other names, which are not limited in the present application. The first device sending the fifth information to the first terminal can also be understood as the first device requesting the capability (request capabilities) from the first terminal.

[0315] Exemplarily, the above-mentioned capability transmission process can only include S320, or can include S310 and S320.

[0316] Based on the above-mentioned scheme, the first device can indicate through the fifth information that the first device feeds back the capability of sensing based on the second communication protocol, so as to trigger the first terminal to report the capability.

[0317] The following introduces an example of an assistance data transfer procedure.

[0318] In some possible implementation manners, before S350, the method further includes S340. The following will be specifically introduced in combination with FIG. 3.

[0319] S340, the first device sends sixth information to the first terminal, and the sixth information can be used to indicate the assistance data. Alternatively, the sixth information can be referred to as the assistance data. Correspondingly, the first terminal receives the sixth information from the first device.

[0320] The assistance data can be used to assist the first terminal to perform sensing. For example, the assistance data can include the position of the second device (for example, a WLAN AP or a UWB anchor point), or the position of the first terminal, and the like.

[0339] The field “location information of the second device” can indicate location configuration information (LCI) of the second device. The LCI can include at least one of latitude, latitude uncertainty, longitude, longitude uncertainty, altitude, or datum.

[0340] The field “location information of the first terminal” can indicate LCI of the first terminal. Examples of the LCI can be found in the foregoing, and will not be repeated here.

[0341] The field “AOI” can indicate configuration information of the AOI. Details can be found in the following description.

[0342] The sixth information can also be referred to as assistance data or other names, which are not limited in the present application. The first device sending the sixth information to the first terminal can also be understood as the first device providing assistance data to the first terminal.

[0343] Based on the above scheme, the first device can indicate one or more data capable of assisting the first device in sensing through the sixth information, thereby helping to further improve the sensing effect of the first terminal.

[0344] In some possible implementation manners, the configuration information of the AOI includes at least one of:

[0345] The boundary coordinates of the AOI. For example, the boundary coordinates of the AOI can be indicated by the LCI.

[0346] The reference tap of the CIR corresponding to the AOI. For example, the reference tap of the CIR can be a first detected tap and / or a strongest tap.

[0347] The CIR window offset of the CIR window corresponding to the AOI.

[0348] The CIR window length of the CIR window corresponding to the AOI.

[0349] The CIR bitmap pattern of the CIR bitmap corresponding to the AOI.

[0350] The reference radius of the CIR corresponding to the AOI can be understood as a reference radius used to indicate the CIR of the AOI. Similarly, the offset of the CIR window corresponding to the AOI can be understood as an offset used to indicate the CIR window of the AOI. The length of the CIR window and the pattern of the CIR bitmap are described above.

[0351] Specific examples of the reference radius of the CIR, the offset of the CIR window, the length of the CIR window, and the pattern of the CIR bitmap are described below, and are not described here in detail.

[0352] In some examples, the configuration information of the AOI can be divided into two categories, which are denoted as AOI example 1 and AOI example 2 below.

[0353] In the AOI example 1, the configuration information of the AOI can include the boundary coordinates of the AOI.

[0354] In the AOI example 2, the configuration information of the AOI can include the parameters of the CIR. In other words, the parameters of the CIR can indicate the AOI. For example, the configuration information of the AOI can include at least one of the following:

[0355] The reference radius of the CIR corresponding to the AOI.

[0356] The offset of the CIR window corresponding to the AOI.

[0357] The length of the CIR window corresponding to the AOI.

[0358] The pattern of the CIR bitmap corresponding to the AOI.

[0359] The above-mentioned configuration information of the AOI can also be referred to as information of the AOI or other names, which are not limited in the present application.

[0360] Based on the above scheme, the first device can indicate the configuration information of the AOI, so that the first terminal can perform sensing within the AOI, and thus the first device can obtain measurement information or sensing results within the AOI.

[0361] In some examples, the first device can actively perform S340.

[0362] In other examples, the first device performs S340 can be based on a request of the first device. Details are described below.

[0363] In some possible implementation manners, before S340, the method 300 further includes S330. Details are described below with reference to FIG. 3.

[0364] S330, the first device receives seventh information from the first terminal, the seventh information being used for requesting position information of the first terminal and / or configuration information of the AOI. Correspondingly, the first terminal sends the seventh information to the first device.

[0365] In some possible implementation manners, S340 comprises: in response to the seventh information, the first device sends sixth information (or referred to as assistance data) to the first terminal.

[0366] Optionally, the seventh information is further used for at least one of the following: requesting information of the second device, indicating whether to feed back measurement information, or indicating whether to feed back sensing result.

[0367] The above-mentioned "requesting A" can be understood as querying A, or indicating the first device to issue A. For example, the seventh information is used for requesting position information of the first terminal, which can be understood as the seventh information being used for querying position information of the first terminal, or being understood as the seventh information being used for indicating the first device to issue position information of the first terminal.

[0368] In some examples, the seventh information can carry an IE as shown in Table 9.

[0369] Table 9 Fields of the seventh information (or referred to as assistance data request)

[0370] The fields of the seventh information can include part or all of the fields in Table 9. The fields of the seventh information can include fields other than those in Table 9, which are not limited in the present application.

[0371] Wherein, the seventh information carries the field "requested AD", which can represent that the seventh information requests the first device to issue the requested AD.

[0372] Exemplarily, the requested AD can include at least one of the following:

[0373] An identifier of the second device.

[0374] Position information of the second device.

[0375] Position information of the first terminal.

[0376] Configuration information of the AOI.

[0377] For example, the requested AD includes the identifier of the second device, i.e., the seventh information carries the identifier of the second device, which can represent that the seventh information is used for requesting the identifier of the second device. Other information is not described herein.

[0378] The configuration information of the AOI indicated by the field "requested AD" can include the information in the aforementioned AOI example 1, or can include the information in the aforementioned AOI example 2. In other words, the seventh information can request the information in the aforementioned AOI example 1, or can request the information in the aforementioned AOI example 2.

[0379] The field "visible second device" can represent the second device visible to the first terminal. In this way, the first device can provide the first terminal with assistance data based on the second device visible to the first terminal.

[0380] The field "stored data" can represent one or more second devices. The assistance data corresponding to the one or more second devices has been stored in the first device. In this way, the first device can avoid repeatedly providing the first terminal with assistance data for the same visible second device.

[0381] The aforementioned seventh information can also be referred to as an assistance data request, an assistance data query, or other names. The first terminal sending the seventh information to the first device can also be understood as the first terminal requesting assistance data from the first device.

[0382] Based on the above scheme, the first device can send data assisting the first terminal in sensing to the first terminal based on the seventh information, thereby further improving the sensing effect.

[0383] Some examples of AOI allocation are introduced below.

[0384] FIG. 4 is a schematic diagram of an implementation scenario provided by an embodiment of the present application. FIG. 4 is only for the convenience of understanding and does not limit the present application. An exemplary assumed scenario is introduced below in combination with FIG. 4.

[0385] Exemplarily, referring to FIG. 4, it is assumed that the AOI of the base station includes region 1, region 2, and region 3. However, due to the limitation of the sensing capability of the base station and terminal 1, the dual-base sensing formed by the base station and terminal 1 can only form good sensing coverage for region 1. For example, the base station and terminal 1 can perform sensing on target 1 in region 1.

[0386] For region 2, the sensing target (for example, target 2) is far away from the base station, and the reflected energy is weak and not easy to detect. However, region 2 has terminal 2 with UWB sensing function. The terminal 2 can form good coverage for region 2. In this way, the terminal 2 can perform sensing on target 2 based on the UWB protocol to obtain measurement information and / or sensing results. The terminal 2 can send the measurement information and / or sensing results to the base station based on the 3GPP protocol through sensing data link 1.

[0387] The coverage area of the region 3 includes an indoor. Since the base station is far away from the terminal and there is a wall blocking, the base station cannot form a good sensing coverage in the indoor. However, there is a terminal 3 with WLAN and / or UWB sensing capability in the region 3. The terminal 3 can form a good sensing coverage of the sensing target (for example, the target 3) in the indoor with the assistance of the WLAN AP or the UWB anchor point in the indoor. In this way, the terminal 3 can sense the target 3 based on the UWB protocol and / or the WLAN protocol to obtain the measurement information and / or the sensing result. The terminal 3 can send the measurement information and / or the sensing result to the base station based on the 3GPP protocol through the sensing data link 2.

[0388] In some possible implementation, the first device can assign different sensing areas to different terminals according to the capability feedback of the terminals. For example, the first terminal can perform S320 to send fourth information (or called capability information) to the first device. The first device can determine the configuration information of the AOI according to the fourth information. The first device can perform S340 to send sixth information (or called assistance data) to the first terminal, which can indicate the configuration information of the AOI.

[0389] Based on the above scheme, the AOI area indicated by the first device to the first terminal can be determined according to the capability of the first terminal, so that the first terminal can be assigned with a reasonable AOI, and the first terminal can be avoided to be assigned with an AOI that cannot perform sensing, thereby improving the sensing effect.

[0390] The following introduces an example of the AOI and the CIR parameter.

[0391] FIG. 5 is a schematic diagram of the AOI provided by the embodiments of the present application.

[0392] Suppose the AOI is 100 meters (m) to 300 m, and taking the double-base sensing as an example. Referring to FIG. 5, the sending end of the probe signal can be denoted as Tx, and the receiving end of the echo signal of the probe signal can be denoted as Rx. In this way, taking the positions of Tx and Rx as the foci of the ellipse, the ellipse 1 to the ellipse 3 can be obtained.

[0393] The ellipse 1 can represent the area of the AOI of 100 m, for example, the sum of the distances of the solid arrow in FIG. 5 can be 100 m. The ellipse 3 can represent the area of the AOI of 300 m, for example, the sum of the distances of the dashed arrow in FIG. 5 can be 300 m. The ellipse 2 can represent a region in the above AOI.

[0394] Alternatively, the AOI can be a range, for example, the ellipse 1 and the ellipse 3 can obtain the AOI of 100 m to 300 m.

[0395] FIG. 6 is a schematic diagram of a CIR window according to an embodiment of the present application. The horizontal axis of FIG. 6 represents time or propagation delay, and the vertical axis represents amplitude.

[0396] According to the AOI, the CIR window can be determined. The offset W of the CIR window can be determined according to the AOI. offset The difference between the propagation delay corresponding to the innermost circle ellipse (e.g., ellipse 1 in FIG. 5) of the AOI and the reference radius can be represented as a. The length W of the CIR window can be determined according to the AOI. length The difference between the propagation delay corresponding to the outermost circle ellipse (e.g., ellipse 3) and the propagation delay corresponding to the innermost circle ellipse can be represented as b.

[0397] An example of a pattern of a CIR bitmap is described below.

[0398] FIG. 7 is a schematic diagram of a CIR bitmap according to an embodiment of the present application. The horizontal and vertical axes of FIG. 7 are described with reference to FIG. 6, and are not described herein again.

[0399] Referring to FIG. 7, each upward arrow can represent a CIR of a path. The CIR bitmap can be used to indicate the paths to be fed back by the first terminal.

[0400] (a) of FIG. 7 shows an example of a single-layer CIR bitmap. Each path can be indicated using one bit in the CIR bitmap. For example, in the case where the bit indicates 1, the first terminal can feed back the measurement information of the path; in the case where the bit indicates 0, the first terminal can not feed back the measurement information of the path. The meanings of the bits indicating 1 and 0 can be exchanged with each other, which is not limited by the present application.

[0401] (b) of FIG. 7 shows an example of a multi-layer CIR bitmap. The multipaths perceived by the first terminal can be divided into a plurality of groups. For example, each group shown in (b) of FIG. 7 can include two paths.

[0402] In the bit bitmap 1, one bit can indicate whether a group needs to be fed back. The group can include at least one path. For example, in the case where the bit indicates 0, the first terminal can not feed back the measurement information of all paths in the group.

[0403] In the bit bitmap 2, one bit can indicate whether a path in a group needs to be fed back. For example, in the case where the bit indicates 1, the first terminal can feed back the measurement information of the path; in the case where the bit indicates 0, the first terminal can not feed back the measurement information of the path. The meanings of the bits indicating 1 and 0 can be exchanged with each other, which is not limited by the present application.

[0404] In the case where the bit bitmap 1 indicates that a group needs to be fed back, the bit bitmap 2 can further indicate which paths in the group need to be fed back. In the case where the bit bitmap 1 indicates that a group needs to be fed back, the bit bitmap 2 can further indicate which paths in the group need to be fed back.

[0405] Based on the above scheme, the first device can indicate the AOI more finely through the CIR bitmap. For example, referring to FIG. 7, through the CIR bitmap, a part of the paths in the CIR window can be selected as the paths that need to be fed back by the first terminal. This process can also be understood as that the first device selects a part of the area between the complete outermost ellipse and the innermost ellipse shown in FIG. 5 as the AOI through the CIR bitmap. In addition, in the above scheme, the first terminal can feed back the CIR data of a part of the paths according to the CIR bitmap, thereby reducing the transmission overhead of the first terminal.

[0406] FIG. 8 is a schematic flowchart of another sensing method 800 provided by an embodiment of the present application. In the following, the first terminal is taken as UE, and the first device is taken as SF. In the following, some network elements involved in the method 800 are introduced.

[0407] The AMF can support the reception of a sensing request, sensing request management, SF selection, or sensing-related messages, etc.

[0408] The gateway sensing center (GSC) can complete the processing of the sensing result request of the SF client, for example, return the sensing result to the SF client. The GSC, as an operation platform of the sensing service system, can complete the functions of user data management, service data management, service subscription information management, data management of service providers (SPs), charging, or authentication of value-added service applications, etc.

[0409] The SF can receive and process the sensing request or sensing-related data request from the AMF, send the sensing result or related sensing data to the AMF, select a sensing method (for example, which can be a single sensing method or a hybrid sensing method), control related sensing measurement based on different sensing methods, calculate sensing assistance data and send it to the UE, or calculate sensing information and estimate the sensing accuracy, etc.

[0410] In the following, the operations of the method 800 are introduced in combination with FIG. 8.

[0411] The UE, the gateway sensing center (GSC), or the AMF can initiate sensing. The method 800 can include any one of S812, S814, or S816.

[0412] S812, the UE sends a sensing service request to the AMF. Correspondingly, the AMF receives the sensing service request from the UE.

[0413] For example, the UE can send the perception service request to a base station (not shown in the figure) serving the UE through a universal mobile telecommunications system (UMTS) terrestrial radio access network (UTRAN) to UE (UTRAN to UE, Uu) interface. The base station can send the perception service request to the AMF through an N2 interface.

[0414] S814, the GSC sends the perception service request to the AMF. Correspondingly, the AMF receives the perception service request from the GSC.

[0415] For example, the GSC can process a perception service request initiated by a SF client, and send the perception service request to the AMF. For another example, when the perception service request is initiated by the SF client, the SF client can send the perception service request to the GSC through an Le interface, and the GSC can send the perception service request to the AMF through an NL2 interface.

[0416] S816, the AMF determines to initiate the perception service request.

[0417] For example, the AMF can decide to enable the perception service for certain UEs (e.g., the UEs shown in FIG. 8).

[0418] S820, the AMF sends the perception service request to the SF. Correspondingly, the SF receives the perception service request from the AMF.

[0419] For example, the AMF can send the perception service request to the SF through an NL1 interface.

[0420] In some possible implementation manners, the method 800 does not include S816, and the method 800 includes S820.

[0421] S830, capability transmission.

[0422] For example, S830 can include S310 and / or S320.

[0423] For example, after the SF receives the perception service request, the UE can report the perception-related capability information to the SF, and the base station serving the UE can report the perception-related capability information to the SF.

[0424] S840, the SF performs perception method selection.

[0425] For example, the SF can perform the selection of the perception method according to at least one of the following factors:

[0426] The perception application requires a quality of service (QoS) of the perception service. For example, horizontal position accuracy, vertical position accuracy, horizontal speed accuracy, or vertical speed accuracy, etc. The perception application can be managed by a perception service client. The SF, as a network element of the core network, can be responsible for perception management. The perception service client can be responsible for the management of the perception application in the outside world. For example, the perception application can be traffic management, or unmanned aerial vehicle flight management, etc.

[0427] The SF configures the perception method. Or, the configuration of the perception method of the SF.

[0428] The activation flag of the perception function of the cell where the UE is located. For example, if the activation flag indicates activation, the perception method of double-base perception can be used, and specifically, the UE and the base station serving the UE can be taken as the execution subject of double-base perception. For another example, if the activation flag indicates inactivation, the method of single-base perception can be used, and specifically, the UE can be taken as the execution subject of single-base perception.

[0429] The perception capability of the UE. For example, the fourth information (or referred to as the capability information) indicates the perception capability of the UE.

[0430] Exemplarily, the perception method can further include performing perception based on a second communication protocol. For example, the perception method can further include performing perception based on UWB capability. Other descriptions of the perception method are described below, and are not described here.

[0431] S850, auxiliary data transmission and perception information transmission.

[0432] For example, S850 can include S330 and / or S340. For another example, S850 can include S360 and / or S380.

[0433] In some examples, if the SF determines that the base station serving the UE needs to participate in perception, the SF can interact with the base station in the related perception process. Exemplarily, the SF can perform similar operations as method 300, and specifically, the first terminal in method 300 can be replaced by the base station. For example, the SF can obtain the measurement information and / or the perception result determined by the base station. For another example, the base station can obtain the auxiliary data from the SF.

[0434] In other examples, if the SF determines that the UE needs to participate in perception, the SF can interact with the UE in the related perception process through a non-access stratum (NAS) message. For example, the SF can perform similar operations as method 300.

[0435] S860, the SF sends a perception service response to the AMF. For example, the perception service response can comprise a perception success, a perception failure, or error information, etc.

[0436] S872, the AMF sends the perception result to the UE. The UE receives the perception result from the AMF.

[0437] For example, in case that S812 is performed, the above S872 can be performed. Illustratively, the AMF can transparently transmit the perception result to the UE.

[0438] S874, the AMF sends the perception result to the GSC. The GSC receives the perception result from the AMF.

[0439] For example, in case that S814 is performed, the above S874 can be performed. Illustratively, the AMF can transparently transmit the perception result to the GSC.

[0440] S876, the AMF transparently transmits the perception result to the related interface service.

[0441] For example, in case that S816 is performed, the above S876 can be performed. Illustratively, the AMF can transparently transmit the perception result to the UE.

[0442] Examples of each mode are introduced as follows.

[0443] Illustratively, for the first mode (or referred to as standalone mode), the execution order can be: S310, S320, S350, S360, S370, and S380. Among them, S310 and S360 are optional operations.

[0444] In the above S320, the fourth information (or referred to as capability information) can indicate that the standalone mode is supported. Optionally, the fourth information further indicates that the perception based on the second communication protocol (for example, UWB protocol and / or WLAN protocol) is supported.

[0445] For example, in the above S380, the second information can indicate the perception result.

[0446] Illustratively, for the second mode (or referred to as UE-assisted mode), the execution order can be: S310, S320, S330, S340, S350, S360, S370, and S380. Among them, S310, S330, S340, and S360 are optional operations.

[0447] In S320, the fourth information (or capability information) can indicate that the UE-assisted mode is supported. Optionally, the fourth information can further indicate that the sensing based on the second communication protocol (e.g., UWB protocol and / or WLAN protocol) is supported.

[0448] For example, in S380, the second information can indicate the measurement information.

[0449] For the third mode (or UE-based mode), the execution sequence can be S310, S320, S330, S340, S350, S360, S370 and S380. Among them, S310, S330 and S360 are optional operations.

[0450] In S320, the fourth information (or capability information) can indicate that the UE-based mode is supported. Optionally, the fourth information can further indicate that the sensing based on the second communication protocol (e.g., UWB protocol and / or WLAN protocol) is supported.

[0451] For example, in S380, the second information can indicate the sensing result.

[0452] In some examples, the mode supported by each sensing method is shown in Table 10.

[0453] Table 10

[0454] For example, the first device-assisted mode can be a next generation radio access network (NG-RAN) node assisted mode. In other words, the first device can be an NG-RAN node.

[0455] The following describes an example of information transmitted between the first device (e.g., SF) and the first terminal (e.g., UE).

[0456] In some examples, the information (e.g., assistance data) transmitted by the first device to the first terminal is shown in Table 11.

[0457] Table 11 Assistance data

[0458] In Table 11, " / " can represent "and / or". The CIR reference diameter in the AOI information can be replaced by a CIR reference diameter type. Table 11 is only an example and does not limit the present application. The information transmitted by the first device to the first terminal can be part or all of the information in Table 11, or information other than Table 11.

[0462] In Table 11, "Yes" and "No" can represent that the first terminal transmits the information to the first device and does not transmit the information in the corresponding mode, respectively. For example, in the second mode, the first terminal can transmit information indicating "BSSID and / or device identifier" to the first device. The information can be carried in a field in the WLAN / UWB information.

[0463] The result information of the above processing can also be referred to as a perception result or other names.

[0464] The process of mapping the WLAN protocol to the 3GPP protocol is described below. The conversion between the 802.11bf protocol and the 3GPP protocol is taken as an example.

[0465] In some examples, the first terminal can perform a perception measurement based on the WLAN (e.g., 802.11bf) protocol to obtain measurement information of the WLAN protocol. The first terminal can convert the measurement information of the WLAN protocol to measurement information of the 3GPP protocol.

N SC can represent the number of subcarriers, N SC can be a positive integer. Exemplarily, the field "H e (a, b, k)" can occupy 16*N SC bits or other number of bits. Wherein, "*" can represent multiplication sign.

For another example, if the field "Rx_OP_Gain_Type" indicates 2, the field "Rx_OP_Gain_Index(a)" can contain the Rx reception gain number of the receive link a.

[0482] The field "CIR path" can contain a value of a CIR path. Each bit in the CIR bitmap can correspond to a CIR path. For example, a bit value of 1 in the CIR bitmap can indicate that the CIR path corresponding to the bit has a value of the CIR path. Each CIR path can include a signed 16-bit real part and a signed 16-bit imaginary part, and be arranged in this order. The above scheme can support using 10-bit, 12-bit or 14-bit values instead of the above 16-bit values. The above real part and imaginary part are optional, and are not limited by the present application.

The description of the device embodiments corresponds to the description of the method embodiments, and therefore, the content not described in detail can be referred to the above method embodiments, and part of the content will not be described again for the sake of brevity.

[0493] The embodiments of the present application can divide the functional modules of the communication device according to the above method examples. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The integrated module can be realized in the form of hardware, software functional module, or a combination of software and hardware. The division of the modules in the embodiments of the present application is illustrative, and is only a logical function division. In actual implementation, another division manner can be used. The following will be described by taking the division of each functional module according to each function as an example.

[0494] FIG. 9 is an exemplary block diagram of the communication device 10 according to an embodiment of the present application.

[0497] As an example but not limitation, the chip system 110 can include a circuit or chip responsible for signal processing (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core.

[0498] Optionally, the chip system 110 can also be provided with a memory (such as a cache) for storing instructions and data. In some embodiments, the memory in the chip system 110 is a cache memory. The memory can save instructions or data that have just been used or recycled by the chip system 110. If the chip system 110 needs to use the instructions or data again, it can be directly called from the memory. This avoids repeated access and reduces the waiting time of the chip system 110, thereby improving the efficiency of the system.

[0499] In some embodiments, the chip system 110 can include one or more interfaces. The interfaces can include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

The code can be stored in a non-transitory computer-readable medium such as system memory or other type of memory. In some cases, the code can not be directly executable by the chip system 110 but can cause a computer (for example, when compiled and executed) to perform functions described herein. In some cases, the memory 120 can include a basic I / O system that can control basic hardware or software operations, for example, interaction with peripheral components or devices.

[0502] Illustratively, the chip system 110 performs various functional applications and data processing of the communication apparatus 10 by running instructions stored in the memory 120.

Optionally, the power management module 140 can supply power to the communication device 10 (e.g., a battery module of the communication device 10) while charging the communication device 10. As an example but not limitation, the power management module 140 can also supply power to devices other than the communication device 10.

[0506] The transceiver 150 can communicate bi-directionally, via one or more antennas, wired, or wireless links as described above, for example, the transceiver 150 can represent a wireless transceiver and can communicate bi-directionally with another wireless transceiver. The transceiver 150 can also include a modem to modulate the packets and to provide the modulated packets to the antennas for transmission, and to demodulate packets received from the antennas. Where the transceiver 150 includes a modem, the modem can be implemented as a software module executed via the processor 130 or as a hardware module.

[0507] In some cases, a wireless device can include a single antenna. However, in some cases the device can have more than one antenna, like the antenna 1 and the antenna 2 shown in FIG. 9, which can be capable of concurrently transmitting or receiving multiple wireless transmissions. Exemplarily, the antenna 1 and the antenna 2 are used to emit and receive electromagnetic wave signals. Each antenna in the communication device 10 can be used to cover a single or multiple communication frequency bands. Different antennas can also be multiplexed to improve the utilization of the antennas. For example: the antenna 1 can be multiplexed as a diversity antenna of a wireless local area network. In some other embodiments, the antennas can be used in combination with a tuning switch. The communication device 10 can transmit files to other devices through a wireless communication function.

[0508] In one design, the communication device 10 can correspond to the first device in the above method embodiments.

In some embodiments, the communication apparatus 10 can also include more or fewer components than those shown in FIG. 9, or combine certain components, or split certain components, or different component arrangements, etc. Alternatively, some components shown in FIG. 9 can be implemented in hardware, software, or a combination of software and hardware, and the terminal device and / or the access network device can add or reduce components on the basis of the structure given in FIG. 9.

[0518] FIG. 10 is a schematic block diagram of the communication apparatus 20 according to an embodiment of the present application.

[0519] As shown in FIG. 10, the communication apparatus 20 can include a baseband unit 210, which can communicate with external devices through a cellular radio frequency (RF) transceiver 220 (for example, when the communication apparatus 20 is a terminal device, the baseband unit 210 can communicate with an access network device through the cellular RF transceiver 220; also for example, when the communication apparatus 20 is an access network device, the baseband unit 210 can communicate with a terminal device and / or a core network device through the cellular RF transceiver 220).

[0520] Exemplarily, the baseband unit 210 can include a computer readable medium / memory.
